Abstract

Abstract: The Final Disposal Site (TPA) is where waste is disposed of at the end of its life cycle. The contamination of groundwater and surface water caused by leachate is one type of pollution generated by TPA. The goal of this research is to determine the level of groundwater and surface water pollution, as well as the correlation of leachate to groundwater and surface water in West Lombok's Final Disposal Site, which is located in Kebon Kongok Hamlet, Suka Makmur Village, Gerung District. The analysis method utilized in this research is the pollution index method and the analysis which consists of a correlation test. The results of the analysis of groundwater pollution levels from samples of resident wells were classified as adequate condition, lightly polluted, and moderate polluted. Meanwhile, surface water is classified as moderately polluted. The results of the TSS correlation test analysis on groundwater turbidity have a positive direction and a strong correlation with a value of 0.643. The results of leachate TSS analysis against surface water TSS have a positive direction and a moderate correlation with a value of 0.357 as well as the COD of leachate against COD of surface water with a value of 0.257. The results of the analysis of leachate BOD to surface water BOD indicate that there is a moderate correlation with a value of 0.475. This is in line with the pollutant index which has a moderate polluted value. Referring to the findings, it is recommended that the urgency of zero waste should be implemented by all parties, not only the government but also all levels of society.
